Singles and Data in the same Dado trunking compartment

What are peoples thoughts on mixing 230V 6491B singles and standard structured wiring data cables in the same compartment of Dado trunking. Although the case I am involved with are supposedly only running next to each other for a short distance it clearly doesn't comply with 528.1 Proximity to electrical services. I have a contractor that isn't concerned by this, however even if the client agrees with a departure from BS7671 I'm still concerned from a health and safety perspective as many of the instances of this are in a medical location.

  • Perhaps not quite the same thing, but on opening this distribution board in an industrial unit, all this guppins associated with a recent solar PV job just fell out. I detest sloppy workmanship and if I had control of the job, your contractor would be making alternative arrangements for the data cables!

  • Looks like CTs and a wireless transmitter ... I'm surprised that worked from inside and earthed steel box  - or was the aerial puking out of a hole somewhere?

  • Nope, all in the DB. Maybe it didn’t work. Judging by the look of things, I don’t think the installer really cared.
